【Precision Double I/D Air-cushion inner barrel】
Create two different inner diameter within inner barrel, because air-flow forward faster than BB, before the BB is not out of the inner barrel, there has to be part of the gas out of the inner barrel, the main purpose is to let the BB rear end of the high-pressure gas, in part relatively large diameter can completely cover a BB, when BB ejected, achieve " front guide " function, more stable flight trajectory starting point, still more straight to the target !!
Use『Precision Double I/D Air-cushion Inner Barrel』with『T-HOP bucking』，more better efficiency !!
